In one embodiment, the mine fault model is comprised of a three-dimensional convolutional neural network including convolutional layers, activation layers, pooling layers, fully-connected layers, and output layers.
In specific implementation, the training process of the mine fault model is as follows:
performing weighted summation convolution operation on the mine historical three-dimensional image with the marked fault type by using a preset three-dimensional convolution layer to extract primary features of the image to obtain a primary feature map;
adding a non-linear feature to the primary feature map through the activation layer;
reducing the dimension size of the primary feature map of the added nonlinear features through a pooling layer;
extracting high-level features from the primary feature map processed by the pooling layer through the full-connection layer;
and converting the high-level features into activation probability through a Softmax classifier in an output layer to obtain the output of the three-dimensional convolutional neural network, and judging whether the training of the mine fault model is finished or not according to the comparison of the output precision of the three-dimensional convolutional neural network and the preset precision.
The embodiment constructs a three-dimensional convolutional neural network model and a corresponding training method, which are different from the conventional two-dimensional convolutional neural network method, and when a three-dimensional image is identified, certain one-dimensional information in three dimensions needs to be averaged or divided into a plurality of channels, so that three-dimensional features cannot be effectively extracted; when constructing a complete three-dimensional convolution neural network, firstly carrying out convolution operation on a three-dimensional image through a convolution layer; then, the convolution result passes through an activation layer, and nonlinear characteristics are added; the result obtained by the upper layer in the three-dimensional convolution neural network passes through the maximum pooling layer, so that the operation amount is reduced, and the operation efficiency is improved.
In another embodiment, the stand-alone control module is further connected with the video acquisition module, the SIP audio call module and the analog audio call module respectively; the video acquisition module is used for acquiring video information in a mine and transmitting the video information to the single-machine control module; the SIP audio call module is used for realizing dialing network call and audio play; the analog audio call module is used for realizing the analog audio call function along the line.
In specific implementation, the single-machine control module is further used for receiving mine video information sent by the video acquisition module, further judging whether an object intrudes into the demarcated area, if so, triggering an out-of-range alarm, immediately and distributively controlling corresponding equipment to stop running, and calling out and displaying images when the out-of-range occurs.
The single-machine control module of the embodiment judges whether an object breaks into a demarcated area according to mine video information, and improves the safety of a mine.
As an optional embodiment, the method for determining whether an object intrudes into the delimited area may be implemented by a deep convolutional neural network model, and the specific process is as follows:
acquiring a plurality of frames of mine video images into which marked objects are inserted to form a training set and a test set;
training the preset deep convolutional neural network model by using a training set, and testing by using a test set until the precision of the output of the preset deep convolutional neural network model meets the preset requirement, thereby completing the training of the deep convolutional neural network model;
and judging whether the input mine video image enters the demarcated area or not by using the trained deep convolution neural network model.
It should be noted that the deep convolutional neural network model is composed of an input layer, a convolutional layer, an activation function, a pooling layer, a full-link layer, and an output layer.
An input layer: the deep convolutional network can directly take the picture as the input of the network, and extract features through training, but in order to obtain better effect, the picture usually needs to be preprocessed, and in addition, in the case of insufficient samples, sample enhancement processing, including rotation, translation, shearing, noise increase, color transformation, and the like, may be required.
And (3) rolling layers: the convolution operation essentially represents the input in another way, and if the convolutional layer is considered as a black box, the output can be considered as another representation of the input, and the training of the whole network is to train the intermediate parameters required for the representation.
It is necessary to add an activation function to the convolutional layer to make the operation nonlinear. The deep convolutional network connects small neural networks in series to form a deep neural network, and two special processing modes are mainly adopted:
1) local receptive fields were used: the neuron is connected with the upper layer neuron adjacent to the neuron, and the final global feature is formed by combining the learned local features.
2) Weight sharing is adopted: when the same convolution kernel operates different local receptive fields, the same weight parameter is adopted, and the parameter calculation amount required in the network operation process can be reduced. Different characteristics of the picture are obtained through the convolution kernels of each layer, specific positions of the characteristics in the picture do not need to be considered specially, and the processing mode has remarkable advantages in the tasks of analyzing and processing the picture.
A pooling layer: the method is a special processing operation for data in a convolutional neural network, reduces the characteristic size of a picture through pooling processing, and can effectively solve the problem of large calculation amount caused by taking the result of the previous layer as input.
Activation function: the convolution operation and the pooling operation in the network are linear operations, while a large number of samples in life are not in a linear relation when being classified, so that a nonlinear element needs to be introduced into the network so that the network can solve the nonlinear problem. A common activation function is the Relu function.
Full connection layer: the layer is the layer with the most consumed parameters in the network, if the input of the fully connected layer is 4 x 100 and the output of the fully connected layer is 512, the layer needs 4 x 100 x 512 parameters; in a typical convolutional layer, if the convolution kernel is 4 × 4 and the output is 512, then only 4 × 512 parameters are needed.
The number of the weights of the deep convolutional neural network is reduced more than that of a conventional neural network, the reduction of the number of the weights means that the complexity of a model becomes simpler, the model is not easy to over-fit, and finally the accuracy and the speed of image recognition are improved.
